Vasyli Medical Custom 3/4 Heat Mouldable Orthotic — Blue
Podiatrist-designed heat-mouldable 3/4 length orthotic with Triplanar Motion Control — ideal for everyday footwear, walking shoes, and casual use.
Everyday biomechanical support for shoes where full-length inserts may not fit
The Vasyli Medical Custom 3/4 Heat Mouldable Orthotic is a semi-custom prefabricated orthotic manufactured by Vasyli Medical, an Australian company founded in 1977 in Adelaide by Phillip Vasyli.
The 3/4 length design covers the heel, arch, and metatarsal head region but stops just before the toes, making it more versatile than a full-length orthotic for fitting into dress shoes, casual shoes, and shoes where a full-length insert does not fit well or creates toe-box discomfort.
The Blue Mid Density version is the general-purpose option, designed for patients of average weight and activity level with general orthotic needs.
This orthotic can be softened in a clinical heat oven and pressed to the individual foot contour for a semi-custom fit. This step is performed by your chiropractor and improves arch contact and biomechanical effectiveness compared with a non-mouldable prefabricated orthotic.
Three density options available
The Blue Mid Density version is stocked at Lakeside Chiropractic as the starting recommendation for most patients.
| Colour | Density | Best For |
|---|---|---|
| Green | Low / Soft | Elderly, diabetic, arthritic patients; those requiring special consideration or very sensitive feet |
| Blue (stocked) | Medium | Average weight and activity level; general orthotic needs; most adults |
| Red | High / Firm | Athletes, high-activity users, bariatric patients; maximum biomechanical control |
Approximate shoe size guide
Sizing is by shoe size. The 3/4 length design means the orthotic does not need to be trimmed at the toe.
| Size | Men's Shoe Size (AU/US) | Women's Shoe Size (AU/US) |
|---|---|---|
| XS | 3.5 – 5 | 4.5 – 6 |
| S | 5.5 – 7 | 6.5 – 8 |
| M | 7.5 – 9 | 8.5 – 10 |
| L | 9.5 – 11 | 10.5 – 12 |
| XL | 11.5 – 13 | — |
Triplanar Motion Control
The Vasyli Custom orthotic range incorporates control of foot function in all three cardinal planes of motion simultaneously.
Rearfoot Angular Restraining Mechanism
Controls frontal plane motion, specifically calcaneal eversion, which is the inward rolling of the heel bone during pronation.
Sustentacula Tali Control
Targets the rearfoot control point at the sustentaculum tali to improve the mechanical efficiency of rearfoot correction.
1st Ray Plantar Flexor Technology
Assists plantar flexion of the first metatarsal column, facilitating hallux dorsiflexion during propulsion.
Sagittal and Transverse Plane Control
Uses arch geometry to control midfoot alignment in forward-backward and rotational planes for three-dimensional correction.
Support for standing, walking, and everyday activity
Controls pronation
Controls excessive subtalar pronation and calcaneal eversion in the rearfoot.
Supports the arch
Supports the medial longitudinal arch in a functionally optimal position.
Improves forefoot mechanics
Facilitates 1st ray plantar flexion for improved hallux function during propulsion.
Cushions impact
geneRx poron material elements cushion the heel and distribute impact loads.
Fits more shoes
The 3/4 length allows use where a full-length orthotic would not fit.
Common presentations with a foot-biomechanical component
-
Heel pain and plantar fasciitis: Arch support and rearfoot control reduce tensile load on the plantar fascia, while heel cushioning helps manage impact discomfort.
-
Knee pain: Rearfoot control may reduce excessive subtalar pronation and the internal tibial rotation that can contribute to knee loading.
-
Back pain: Controlling excessive pronation at the foundation can reduce compensatory spinal loads transmitted through the kinetic chain.
-
General lower limb overuse conditions: Biomechanical corrections may support Achilles tendinopathy, shin splints, hip pain, and sacroiliac joint dysfunction where foot mechanics contribute.
-
Everyday fatigue and foot comfort: Arch support, rearfoot control, and cushioning can reduce cumulative loading fatigue for patients who spend long hours on their feet.
-
Chiropractic home care: Orthotics can complement chiropractic care by addressing the foot-originated mechanical input that can perpetuate spinal and pelvic problems between visits.
How this compares to the Vasyli Trevor Prior Sports Orthotic
-
The Vasyli Custom 3/4 Blue is a general-purpose everyday orthotic. It is appropriate for walking, casual, and most everyday footwear.
-
The Vasyli Trevor Prior Sports Low Profile Orthotic is specifically designed for low-profile sports footwear such as athletic trainers, cleats, and sports shoes.
-
Many patients benefit from having both: the Vasyli Custom 3/4 for everyday and dress footwear, and the Trevor Prior Sports for athletic or training footwear.
Fit the orthotic and increase wear gradually
-
Remove the existing factory insole from the shoe if possible. Insert the Vasyli orthotic with the heel seated fully into the heel of the shoe.
-
The 3/4 length should fit comfortably without reaching the toe box. No trimming should be required for most standard footwear.
-
Ensure the arch of the orthotic aligns with the natural arch of your foot. If there is a pressure point or the arch feels too high, heat moulding by your chiropractor will improve the fit.
-
For heat moulding, bring the orthotic to your next chiropractor appointment. Your chiropractor can heat-mould the shell to your specific foot contour in the clinic.
-
Begin with 2 to 4 hours of wear on the first day and increase by 1 to 2 hours per day over 1 to 2 weeks.
-
Use in all footwear worn for extended periods. The 3/4 length makes this practical for a wide range of shoe types.
-
Replace when the shell shows significant compression or flattening, typically 12 to 18 months with regular daily use.
Important — please read before use
- An adaptation period is important. Do not begin wearing the orthotic all day on the first day.
- If you experience increased pain, new knee discomfort, or lower leg symptoms after introducing the orthotic, stop use and consult your chiropractor.
- Heat moulding should be performed by a trained clinician. Do not attempt to soften the shell at home without specific guidance.
- This is a prefabricated orthotic. Heat moulding improves fit and function, but it does not replicate a fully custom orthotic cast from your foot.
- This product is a supportive tool, not a standalone treatment. It is most effective when combined with chiropractic assessment and treatment of the underlying cause of your symptoms.
